MK200 Piston vs MK2

[Hethen57]

I guess I will have to pick some
of that stuff up and do it the way it was intended. Thanks so much for the tip!

Dow 111 is all I use. It works well, is less expensive and does not separate like some of the other lubes do. IMO, it's fine for nitrox at rec levels (<36).

Very good..that is what I will use. Thanks again herman!

As others have said, leaks from the ambient chamber on Mk2’s are the result of faulty o-rings or a problem with the body. Here is a Mk200 that had an ambient chamber leak with air coming out of the chamber holes. IP was constant at 128 psi. A fifteen minute repair with new o-rings on the piston, and it’s ready to go back in the water.
